Sorry  one typo: problem is the same....



location cli-prefer-aapche aapche role=Started 10: sles2

to:

location cli-prefer-aapche aapche role=Started inf: sles2



It keep change to infinity.




my configuration is:

node sles1
node sles2
primitive filesystem Filesystem \
       params fstype=ext3 directory="/srv/www/vhosts" device="/dev/xvdd1" \
       op start interval=0 timeout=60 \
       op stop interval=0 timeout=60 \
       op monitor interval=20 timeout=40

       op start interval=0 timeout=20s \
       op stop interval=0 timeout=20s \
       op monitor interval=10s timeout=20s

       placement-strategy=balanced \
       expected-quorum-votes=2 \
       dc-version=1.1.12-f47ea56 \
       cluster-infrastructure="classic openais (with plugin)" \
       last-lrm-refresh=1440502955 \

and after migration:

Hi list,



I have configure simple cluster on sles 11 sp4 and have a problem with “auto_failover off". The problem is that when ever I migrate resource group via HAWK my configuration change from:


location cli-prefer-aapche aapche role=Started 10: sles2

to:

location cli-ban-aapche-on-sles1 aapche role=Started -inf: sles1


It keep change to inf.


and then after fance node, resource is moving back to original node which I don't want. How can I avoid this situation?

my configuration is:

node sles1
node sles2
primitive filesystem Filesystem \
       params fstype=ext3 directory="/srv/www/vhosts" device="/dev/xvdd1" \
       op start interval=0 timeout=60 \
       op stop interval=0 timeout=60 \
       op monitor interval=20 timeout=40
primitive myip IPaddr2 \
       params ip=x.x.x.x \
       op start interval=0 timeout=20s \
       op stop interval=0 timeout=20s \
       op monitor interval=10s timeout=20s
primitive stonith_sbd stonith:external/sbd \
       params pcmk_delay_max=30
primitive web apache \
       params configfile="/etc/apache2/httpd.conf" \
       op start interval=0 timeout=40s \
       op stop interval=0 timeout=60s \
       op monitor interval=10 timeout=20s
